Appropriate for removing labels of bottles and oil glasses

The invention relates to a device for removing labels from bottles and glasses, wherein the bottles, as the bottles and glasses to be treated are called below for the sake of simplicity, via one endless conveyor are conveyed in a bent path through a series of tanks, in which a softening process and blasting is performed to clean the bottles and apply the labels therefrom remove"

In the known devices of this type is usually more than one tank is required in which the labels are removed from the bottles »This has the consequence that the cleaning fluid, which is labeled with ' sets is »must be removed from these tanks and that The presence of loose labels hinders the washing process and the secretion difficult powerful.

To eliminate these disadvantages »is in agreement provided with the present invention, the bottles first through one or more soaking tanks and then dlirch to lead a label removal tank, whereby in the latter tank the bottles during their immersion in the liquid present therein, jets of Cleaning liquid are exposed, which are arranged below the liquid level nozzles or outlets and the rays are directed from the neck end of the bottles towards the bottom of the same. It is provided that the removed labels on the inside of the conveyor can be brought »when this · with some of the liquid removed, which preferably is then separated from the labels and returned. By suitable · arrangement of the conveyor track of the Conveyor and through openings provided in the associated bottle guide, which is located on the opposite side Side of the one below the liquid level *

If jets are provided, there is a substantially closed zone in the conveyor guide in this tank provided, in which all removed labels are rinsed.

For a better understanding of the invention the same will be given described with reference to the accompanying drawing, wherein the drawing shows schematically an embodiment for a label removal tank according to the invention in Vertical section shows.

This tank 1 shown in the drawing has an inlet and an outlet opening 2 and 3 for the implementation of a conveyor h , which is only indicated by its center line and runs in the direction of arrow A and is carried by conveyor rollers 5, of which only one is indicated. The conveyor runs over guides 6 and carries a series of open receptacles, only a few of which are also shown, in which bottles B are held in a known manner.

As can be seen from the drawing, the bottle conveyor runs first a little backwards downwards, then horizontally, then a little backwards upwards, and a substantial part of this loop-shaped path runs below the liquid level, which is indicated by L. A bottle guide 8, which in a known manner the conveyor h

is assigned and holds the bottles in the receptacles, runs in the same path as the conveyor and is arranged to have a label collection zone C within the conveyor loop is limited. It is to be noted that this conveyor track does not simply run down and up in the usual way, as in the known tanks for vashing and removing the labels from the bottles is common, but runs in two horizontal parts, in which the bottom ends of the bottles are directed upwards and downwards another time.

Outside this conveyor loop, nozzle sets 9 and 10 are arranged on the upwardly and downwardly directed parts, which jets of washing liquid through the open receiving bottoms and towards the top of the bottles, face down on the sides of the same to remove the labels. The rays then run through grids 11 and 12, which are parts of the bottle guide 8 and guide the labels into the collection zone C. These nozzles 9 and are arranged below the liquid in the tank and it has been found to be advantageous in practice that this The arrangement of the jets makes it easier to remove the labels from the bottles and to transfer them to the collection zone supports·

A suction pump, not shown, draws the liquid and removed labels from this zone and guides them through a self-cleaning rotating filter or other suitable devices for collecting the removed Labels. The filtered liquid is then fed to a nozzle set 13 which has a series of liquid jets upwards into the bottles before they leave the tank 1 on their conveyor track Liquid falls into a trough or on an inclined surface 14 which the liquid falls onto the opening ends the bottles straighten "when they leave the tank liquid" When these bottles are conveyed further and are reversed in the process, the liquid they contain will flow to the discharge end of the channel and meets the bottles » which emerge from the tank liquid. The bottle guide 8 has a further grate 15 which is arranged opposite the guide or guide surface and through which every additional label that has been washed off here is fed into the collecting zone C * This arrangement allows all labels in a tank within the conveyor loop are collected and the cleaning liquid · which flows through the grids of the bottle guide 8 caused by the power of its rays and by the suction pump the loosening and the predetermined movement of the distant Labels.

Also during the movement of the bottles on the lower horizontal part of the conveyor this reversed in the recordings, whereby the recordings hold the already loosened labels, which then pass through the inlet ends of the recordings sucked into the collection zone when the bottles reach the downstream * grate 12 of the bottle guide

The use of liquid jets arranged below the liquid level has the advantage that only a small amount of foam occurs and the turbulence within the liquid is kept low, which leads to Improvement of the label removal contributes.

The invention includes everything that is contained in the description and or shown in the drawing is, including what deviates from the specific Embodiments are obvious to a person skilled in the art
